OIL-BURNER.

Specification of Letters Patent.

Patented A110'. 26,1913.

Application 'filed February 9, 1912. Serial No. 676,655.

To all whom t may concern:

Be it known that I, GATLAND GILBERD, a citizen of New Zealand, residing at Hender son, in the Province of Auckland, in the Dominion of New Zealand, have invented new and useful Improvements in Oil- Burners, of which the following is a specilication.

My invention refers to improvements in oil burners and the objects of my improvements are, 1st, to provide a suitable coil pipe connection, through which the oil vapor passes from the oil vessel to the gas flame ring; 2nd, to provide means for adjusting the size of the opening, through which the oil vapor passes before mixing with the air, and entering the gas flame ring. I attain these objects by the apparatus illus trated in the accompanying drawings.

Figure (l) is a plan of the apparatus, the supporting frame of the gas ring being removed. Fig. (2) is a vertical section through the center of the gas flame ringthe pipe coil and oil vessel at M N Fig. (l). Fig. is a side elevation of the hollow ring.

Referring to Fig. (l) A is a horizontal hollow metal ring, with a hollow branch B on one side, and open to the hollow ring. The end of this hollow branch is shaped into a conical opening C and provided with a nut-a stalling box and a gland. A threaded tapered rod or needle valve D works into the conical opening C through the nut and stalling box. By turning the wheel at the end of the tapered threaded spindle, the size of the opening in the conical nozzle can be regulated to the required dimensions. From the center of the oil reservoir is led a vertical pipe E and laid in abouttwo turns on the upper surface of the hollow metal ring A and terminating in connection with the annular space, around the tapered needle rod D. Suitable openings F are made on each side of the branch pipe B and near the end of the conical nozzle C as shown Figs. (l) and (3). The upper surface of the gas flame ring is perforated at suitable intervals between the coils Figs. (l) and (2).

Operation as follows: The oil in the reservoir or body of the lamp H Fic'. (2) is under air compression by means-of a pump and rises through the Vertical pipe E. Then met-hylated spirit is ignited in the cup K, the oil rises in the pipe, and passes through the coils E, to the conical nozzle Fig. Here the small opening that is required for the passage of the oil vapor is regulated by the. threaded needle valve. The oil vapor then mixes with the atmospheric air, which enters the hollow branch B, through the side openings at F, Figs. (l) and The inflammable mixture now impinges on the inner wall of the hollow ring, divides down the sides and issues through the perforations at the top of the ring.

If, from any cause, in the use of the lamp, the nozzle becomes clogged, the opening can be cleared by screwing in or out the needle valve as may be required.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed I declare that what I claim is In an oil burner, in combination, a hori zontal hollow ring shaped member, provided with perfor-ations in its upper surfa ce, a. conduit communicating with said ring and provided witli an air inlet, said conduit being in the same horizontal plane as said ring shaped member, a closed oil reservoir positioned bel-ow said member, a pipe leading upwardly from said reservoir and communicating with said conduit, said pipe being provided with horizontally positioned coils adjacent the upper surface of said ring shaped member and positioned on opposite sides of said perforations, a spirit cup operatively associated with the upwardly extending portion of said pipe, and means for regulating the flow from said pipe into said conduit.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GATLAND GILBERD.
